The clamp under the sprocket cover can be seen on page 259 fig K7-25 - again from the same manual. Pat
Pat and Scottly,
Many thanks.
Pat,
My manual is the same as yours but the pictures have been copied one too many times. No real discernable definition to them. Your first 2 I saw with your help knowing where to look. Fig K7-25 is impossible to see clearly. Kinda looks like it's under the left hand bolt vs the right hand bolt in Scottly's picture?? Can you confirm that. Wanna trade shop manuals?
Oh, I take that back. It appears to be under the shorter bolt below the top 2 longer bolts?? Perhaps?
Terry,
I'll still send some pics even if the other guys decided to help and you didn't !

Send me your pix anyway so I can drool over that sweet bike (even if it's not yer F)
